Room 13 recently went to the awesome TECHFEST on Thursday the 11th of September 2014. We watched and took part in 3 different activities.They were The Best of Science Show, Maths Around the World and Rock Detectives.Our favourite was The Best of Science Show. The man who was doing The Best of Science Show blew up a balloon with hydrogen, he lit it up with a match and if it exploded it was hydrogen, if it didn’t explode it wasn’t hydrogen. It did explode so it was hydrogen. We had an AWESOME time!!!
